摘　　要：互通式立交在方案布置时,需要着重考虑与周边建设条件的关系,进行详细的方案论证。本文以温州市诸永高速公路延伸线增设温州北站互通为例,分析了互通方案布设所受的限制控制因素,提出了T型互通+分离式桥梁、T型互通+叠层匝道桥梁和左转迂回式匝道+整体式桥梁等方案做比选,最终确定采用T型互通+叠层匝道桥梁方案做为推荐方案。该方案为条件受限下互通选型和设计提供一种新思路。When designing an interchange,it is necessary to focus on the relationship with surrounding construction conditions and conduct detailed program demonstrations.This article takes the addition of Wenzhou North Station Interchange on the extension line of Zhuyong Expressway in Wenzhou City as an example,analyzes the restrictive control factors of the layout of the interchange plan,and proposes schemes of T-type interchange+separated bridge,T-type interchange+stacked ramp bridge and left turn detour ramp+integral bridge for comparison and selection,and the T-shaped interconnection+stacked bridge was finally decided as the recommended solution.This solution provides a new idea for Interchange type selection and design under limited conditions.
